Generation of facial emotional expressions based on psychological theory

Facial expressions are an important aspect in affective social computing. They express internal states of robots during social interac- tions. In this paper we present the use of Scherer’s psychological theory to express facial emotions. This theory has the advantage of linking cogni- tive and emotional processes. We have implemented a part of this theory on a robot: iCat. We present results by comparing several representations of the same emotions.
